This is Really Awesome - we are a Non-Profit working with over 145 Rescue & Shelter organizations in Texas and we have been thinking about starting a Wheelchair loaner program for years now but this 3D printing idea opens a whole new opportunity for so many in need. We are thinking about purchasing a printer and making wheelchairs with front, back and all 4 wheels do you have any suggestions, ideas or advice for us: ) Thank you for all you do and for Helping Us Help Them!
